Manual Operation; Returning To Normal Operation - FAAC 770 Bedienungsanleitung

• smooth gate movement, with no stiff points;
• min. clearance between bottom edge of gate and ground as in
fig. 6a (where 's' = thickness of guide bracket);
• mechanical travel stops.
If any welding or brazing has to be done on the gate, do
this before installing the automation system.
The condition of the gate directly affects the reliability and
safety of the automation system.
4.2. INSTALLATION OF LEAF SUPPORTING FOUNDATION
BOX
Proceed as instructed below:
a. existing gate with fixed hinges:
• Remove the gate;
• Remove the bottom hinge.
If the gate cannot be removed, place blocks under its bottom
edge to support it.
b. existing gate with adjustable hinges:
• Remove the bottom hinge;
• Slacken off the top hinge;
• Swing the leaf around the axis of the top hinge (Fig. 4).
c. New gate to be installed:
• Fit just the top hinge. If possible use an adjustable hinge;
1. Dig out a hole for the foundation box as shown in Fig. 5.
Depending on the nature of the ground, it may be necessary
to cast a bed of quick-setting concrete at the bottom of the
hole to avoid subsidence in future.
2. Place the foundation box in the hole, respecting the dimen-
sions given in Fig. 6a - 6b - 6c. The center of the pivot on the
foundation box must be perfectly aligned with the leaf's axis
of swing (Fig. 6a - 6b - 6c).
Use of the gear plate for 180° opening allows the housing
case to be embedded in any position. The alignment of the
pin present on the case with the leaf's axis of rotation must
be respected at all times (Fig. 6c).
3. Lay down a PVC tube of diameter 35 mm through which to
pass a 4 core electrical cable. The tube must reach from the
box the control unit (Fig. 7 rif. a). Lay a second tube to drain off
rain water, from the box to the nearest drain (Fig. 7 rif. b).
4. Fix the box in place with a casting of concrete.
4.3. SETTING UP THE GATE
Wait for the cement to set before starting this operation.
1. Assemble the release levers on the support bracket, and fit
the latter on the pivot in the foundation box, also inserting the
ball supplied (Fig. 8).
Grease both the pivot and the ball.
Do not lubricate the release system for any reason.
2. Prepare the guide bracket, as follows:
• use a "U" profile with dimensions indicated in Fig. 9;
• ascertain the correct location of the leaf on the "U" profile
with reference to the axis of rotation (Fig. 10a or 10b) ; seal
the "U" profile on the post side with a plate, as shown in Fig.
10a or 10b.
3. Carefully weld the guide bracket to the support bracket (Fig.
11).
4. Fit the gate into the guide bracket and fix the top hinge in
place.
To ensure trouble-free operation, do NOT weld the gate leaf to
the guide bracket or to the support bracket.
5. Manually verify whether the gate opens and closes completely
and smoothly, stopping at the mechanical travel stops.
5.4. INSTALLING THE OPERATOR
1. Open the gate leaf.
2. Place the operator on the fastening screws on the foundation
box, and fix it by means of the nuts and washers supplied (fig.
13a and 13b).
In order to determine the exact position of the operator with
the levers for 110° and 140° opening, please refer to fig. 12.
In any case the operator pinion must be on the opposite
side of leaves opening direction.
3. Manually close the leaf and fit the driving levers supplied, as
shown in Fig. 13a.
In order to determine the exact position of the operator, gear
plate for 180° opening (Fig. 13b) and the required settings,
please refer to the instructions enclosed.
For systems with 110° and 140° opening it is possible to fit
the (optional) open (Fig. 14 rif.a) and close (Fig. 14 rif.b)
mechanical stops inside the housing case. For installation
details, please refer to the relative instructions.
Grease the operator pinion and the fixing pivots of the two
levers.
Do not oil the gears of the gear plate.
Do not lubricate the release system for any reason.
4. Fasten the box cover by means of the screws supplied (Fig.
15).
5. Install the second operator, if required, repeating the opera-
tions described above.
Install the electronic control unit, referring to the dimensions
6.
indicated in the relevant instructions.
5. START-UP
Before attempting any work on the system or on the operator,
always turn off power.
Observe points 10, 11, 12, 13, 14 of the GENERAL SAFETY OBLIGA-
TIONS.
Observing the instructions in Fig.3, lay the raceways and make
the electric connections of the control board to the selected
accessories.
Always separate power cables from control and safety cables
(push-button, receiver, photocells, etc...). To prevent any electric
noise whatever, use separate sheaths.
1. Program the control board according to your needs observing
the concerning instructions.
2. Switch on power to the system and check the condition of the
LEDs according to the table of the control board instructions.
6. TEST OF THE AUTOMATED SYSTEM
Check operating efficiency of the automated system and all ac-
cessories connected to it.
Hand the "User's Guide" page to the Client, explain correct opera-
tion and use of the operator and indicate the potentially dangerous
areas of the automated system.

7. MANUAL OPERATION

Should the need arise to operate the gate manually because of a
power failure or malfunction, the release device with key fitted on
the support bracket (Fig. 1 rif. f) makes it possible to release the
system both from the inside and from the outside.
To operate the leaf manually, proceed as follows:
Cut power to the system.
• open the lid of the lock (Fig. 16 rif. a)
• insert the release key in the lock (Fig. 16 rif. b)
• turn the key in the direction of the post, as far as it will go (Fig.
16 rif. c)
• pull the lever out (Fig. 16 rif. d)
• operate the leaf manually.

8. RETURNING TO NORMAL OPERATION

To avoid an involuntary pulse from activating the gate during
the manoeuvre, before re-locking the operator , switch off
power to the system.
• push the lever back into its home position (Fig. 17 rif. a)
• insert the release key in the lock and turn it in the direction opposite
the post, as far as it will go (Fig. 17 rif. b)
• operate the leaf manually until the lock is engaged in the locking
bracket (Fig. 17 rif. c)
• close the lid of the lock.
• make sure that the gate cannot be moved manually.
• restore power to the system.
